R. Winn HardinROSKILDE, Denmark -- A new process that impresses holographic optical elements onto polymer rolls could significantly reduce the cost of keeping roads safe at night. According to Ibsen Micro Structures developmental engineer Michael Rasmussen, street signs and reflectors embedded along roads depend on retroreflection as a passive light source. Retroreflection is the process of turning a light ray around and sending it back to its source -- in this case the headlights of an automobile. The results are highly reflective road signs, paint or clothing that keep both drivers and pedestrians safer...Read full articleRelated content from Photonics MediaArticlesPump Laser Modules Show Promise for Ophthalmologic TreatmentsResearchers at the Berlin-based Ferdinand-Braun-Institut (FBH) developed a pump laser module for ophthalmologic treatments.
